RAID 3 Data Recovery Services

DataTech Labs® provides fast, professional RAID 3 data recovery services. Our expert recovery engineers will work around the clock to ensure that your critical data is retrieved as quickly as possible. We understand that each customer’s situation is unique, so we will analyze each hard drive in your RAID 3 array to determine the best recovery method for each of our clients.

RAID 3 Data Recovery Services

A RAID 3 requires at least three hard disks, and it introduces the concept of parity. Parity is a block of data that is not user accessible, but is an XOR calculation result of the user data written to the other drives. If any of the hard drives fail, data can be reconstructed by reversing the XOR equation. There is a slight lag in performance because this calculation takes a small amount of additional time.

What is RAID 3?

RAID 3 systems require a minimum of 3 drives and the disks must have synchronous spinning for the array to work. RAID 3 arrays also have a dedicated parity drive. A parity drive, instead of working as storage disk, works as a reconstruction of data should one part of the array fail. Parity bits also work as a form of error protecting code. The data on these drives are processed on a byte level and data is written in parallel throughout all the drives. Because of the additional need for sequential writing, performance is slower on bigger arrays like RAID 3 and higher.

Because of their impressive transfer rates, they are ideal for long sequential read and writes such as large video editing. However, RAID 3 arrays are rarely used and are fairly obsolete in present day. Now, most RAID 3 arrays are replaced with RAID 5 arrays.

Some typical scenarios that cause RAID 3 data loss include:

  • RAID array/controller failure
  • Server registry configuration lost
  • Intermittent drive failure resulting in configuration corruption
  • Accidental reconfiguration of RAID drives
  • Multiple drive failure
  • Accidental replacement of media components

What to do when a RAID 3 Fails.

Although the first instinct is to rebuild the array, doing so can cause irreversible damage to the drives and risk decreasing chances of a successful recovery. Immediately turn the device off and call a professional data recovery lab to get assistance on what to do next

DataTech Labs Experience with RAID 3

At DataTech Labs, our RAID recovery engineers have extensive experience with RAID 3 data recovery. We have developed custom and proprietary tools and techniques to successfully perform RAID 0 data recovery.

If you’ve been to another recovery company and they have failed your job, call us, we repeatedly recover where others fail.
